You can update and change the game how much you want and the results will be the same at the end , you have to be fair and give equal booster to everyone, from 5 video a day to another 30 video or more the one with 5 can do nothing except build mutants and tanking (and is cheap and easy to build).
The irony about all this is manager with 30 video a day and tokens buyer cry to mommy when losing and call cheaters the managers with no video and no money as they are smart and creative .
Remind yourself this is a computer not football and smart brain always find a way around specially when you are not fair with them.
This games I like it a lot and not have intention to stop but until is not equal to everyone I support mutants and in 2 or 3 season from now every good team will be at 1% when need to be and 340 % because now is set it up to be this way and there it can be very boring.

This is my opinion and not a complain and hope to see improvements and 3D in the future.

When video are not available in some country give free booster to these manager for they can compete equally but until this not happening don't call them cheaters when they find a way to stay in the game.
